"Concerns about the financial health of the biggest U.S. mortgage finance company had driven Fannie Mae's borrowing costs to the highest since March the previous week and its shares had tumbled 45 percent on the New York Stock Exchange. Investors in Asia, the biggest foreign owners of Fannie Mae's $3 trillion of bonds, were asking the Treasury to bolster the government- sponsored company and its smaller competitor, Freddie Mac, said three people with knowledge of the talks.

Paulson told Mudd he had a plan to restore confidence in Fannie and Freddie, the core of the Bush administration's efforts to revive the U.S. housing market. ``At that point, the proposal began to take form,'' Mudd, 49, said in an interview. ``We're trying to solve a crisis of confidence. Would this do it?''

The next afternoon, before financial markets opened Monday in Asia, Paulson announced the rescue plan, saying he would seek authority to buy unlimited equity stakes in the companies and their bonds if needed, while the Federal Reserve would lend directly to Fannie and Freddie. Congress included the proposals in a broader housing bill that President George W. Bush signed into law last week.

Asian investors were among the most important groups to soothe because central banks, financial institutions and funds in the region own $800 billion of Fannie Mae and Freddie Mac's $5.2 trillion in debt, according to data compiled by the Treasury. U.S. officials were concerned that sales from the region would push lending rates higher, said the people, who declined to be named because the discussions were confidential."
